Sure you'll need to find an open source library for encoding the
barcodes. One example might be http://qrcode.sourceforge.jp/
Then you can write a qgis plugin that integrates into the app. Basically
a prompt that asks for the information need to create the barcode and
then places the results on the map composer or map window (kinda like
the north arrow).
Note you could cheat for now and create it oustide the app and make it a
north arrow or just drop it on top of the final map.
